I-SpO2 imele iperipheral capillary oxygen saturation, uqikelelo lobungakanani beoksijini egazini.Ngokuthe ngqo, yipesenteji ye-oxygen hemoglobin (i-haemoglobin equlethe i-oksijini) xa kuthelekiswa nesixa esipheleleyo se-hemoglobin egazini (i-oxygenated and non-oxygenated haemoglobin).
I-SpO2 luqikelelo lwe-arterial oxygen saturation, okanye i-SaO2, ebhekisela kwisixa se-oksijini ye-hemoglobin egazini.
IHemoglobin yiprotheyini ethwala ioksijini egazini.Ifumaneka ngaphakathi kweeseli ezibomvu zegazi kwaye izinike umbala wazo obomvu.
I-SpO2 inokulinganiswa nge-pulse oximetry, indlela engathanga ngqo, engekho-invasive (ithetha ukuba ayibandakanyi ukuqaliswa kwezixhobo emzimbeni).Isebenza ngokukhupha kwaye emva koko ifunxe iliza elikhanyayo elidlula kwimithambo yegazi (okanye ii-capillaries) kwincam yomnwe.Ukwahluka kwamaza okukhanya adlula emnweni kuya kunika ixabiso lomlinganiselo we-SpO2 kuba iqondo lokuzaliswa kweoksijini libangela umahluko kumbala wegazi.
Eli xabiso limelwe ngepesenti.Ukuba i-Wingings Pulse Ox™ ithi i-98%, oku kuthetha ukuba iseli nganye ebomvu yegazi yenziwe ngama-98% e-oksijini kunye ne-2% yehaemoglobin engenawo umoya.Amaxabiso aqhelekileyo e-SpO2 ahluka phakathi kwe-95 kunye ne-100%.
I-oksijeni yegazi elungileyo iyimfuneko ukuze unikeze amandla izihlunu zakho ezifunekayo ukuze usebenze, okwandisa ngexesha lomsebenzi wezemidlalo.Ukuba ixabiso lakho le-SpO2 lingaphantsi kwe-95%, loo nto ingaba ngumqondiso we-oksijeni yegazi engafanelekanga, ebizwa ngokuba yi-hypoxia.
